A 943931是一种H4R(组胺受体亚型之一)拮抗剂[1],对人(Ki = 5 nM)、大鼠(Ki = 4 nM)和小鼠(Kb = 6 nM )H4Rs具有高亲和性[2]。
H4R是组胺的4种已知的G蛋白偶联受体(H1、H2、H3和H4受体)之一,可介导组胺的生理功能[3]。
HMC-1细胞与300 nM的A 943931孵育20 min可YZH4R诱导的ALDH2活性增加[4]。在小胶质细胞中,A 943931在10 μM浓度下可部分YZ浓度为0.1 μg/ml的组胺诱导的TNF-α和IL-6释放[5]。在来源的肥大细胞中,A 943931可YZ组胺诱导的形状变化(IC50 = 0.38 μM)[6]。
在小鼠中,A 943931在33 μmol/kg剂量下腹腔给药可有效YZH4R激活剂诱导的发痒[6]。在多个临床前模型中,H4R与炎症有关[7]。在多个物种的体外和体内试验中,A 943931具有优异的拮抗活性,并有良好的口服生物利用度(90%)和优异的代谢稳定性。该物质在大鼠疼痛模型中具有良好LX,在小鼠中是一种良好的KY药剂[8]。在大鼠体内,A 943931的口服生物利用度为34%,半衰期为2.6 h[2]。A 943931可在退缩模型中有效减弱诱导的急性炎性疼痛,在大鼠机械和热痛觉过敏模型中可减弱卡拉胶诱导的急性炎性疼痛[9]。
